If parking the bus and winning was such an easy job, Allardyce would have 20 CL's titles in the bag. Parking the bus away from home, playing to your strengths and analyzing the opposition is different than parking the bus and hoping to win. By just 'parking the bus', he has outscored us this season already by 5 goals.
And if anyone recalls his time at RM, I do not recall him parking the bus. He plays his best team to the best tactic, according to the situation. He has a Plan A, B, C, D, E & F. We have motivation, spirit and determination to pass the ball sideways. I know which one I'd pick as a football fan.
